摘　　要：青藏高原东缘作为调节高原物质向东挤出的构造转换带,发育了高密度活动断裂和具有高频强震活动,而且地质地貌复杂,人口相对密集,因而成为我国地震灾害问题最突出的地区之一。近年来,伴随地震灾害风险普查和活断层探测等工作的深入,对青藏高原东缘及邻区强震构造及相关地震灾害的调查研究程度得到不断提升。为了及时交流相关的研究成果,支撑区域防震减灾和地质安全评价等工作,《地震科学进展》编辑部组织了“青藏高原东缘及邻区强震构造”成果专辑2期。此期专辑共征集优选了强震构造、地震与灾害和构造地貌相关领域的代表性学术论文11篇,希望这些成果可进一步提升对区域强震构造特征、地震活动风险及触发地质灾害规律等的认识,从而为防范强震灾害风险提供科学依据或参考。The eastern margin of the Tibetan Plateau is a tectonic transformation belt regulating the eastward extrusion of materials from the plateau.This area not only has high density active faults and high frequency strong earthquakes,but also has very complex geological and geomorphological features.So it is one of the most serious earthquake hazard areas in China.In recent years,with the development of seismic hazard risk survey and active fault detection,the investigation and study on the strong earthquakes,seismogenic structures and related earthquake hazards in the eastern margin of the Qinghai-Tibet Plateau and adjacent areas have been continuously improved.In order to timely exchange relevant research results and support regional earthquake prevention and hazard reduction and geological safety evaluation,the journal editorial department of Progress in Earthquake Sciences organized two special topics of“The strong earthquakes and seismogenic structures in eastern margin of Tibetan Plateau and adjacent areas”.In this special topic,a total of 11 representative articles in the fields of strong earthquake structures,earthquake and hazard and tectonic geomorphology were collected and selected.We hope that these new research results may further improve the understanding on regional strong earthquake structural characteristics,seismic hazard and the law of triggering geological hazards,so as to provide scientific basis or reference for preventing the risk of strong earthquake hazards.
